In this case, the Plaintiff, Lewis, wants to create a class action against the Defendant, Epic. Epic forced its employees to sign an arbitration agreement that prevents class actions. Lewis argued, and the court below found, that forcing employees to sign arbitration that prevent class actions violates the National Labor Relations Act, which gives the employee the right to engage in concerted activities for their mutual aid or protection. Essentially, the class action is a concerted activity that the employer is violating.
